3 Claims. (Cl. 36-40) This invention relates to ladies shoes and more particularly to the construction of a spike-type heel for ladies shoes.

Heretofore spike-type heels have been provided wherein the more serious difficulty was not only lack of rigidity but an effective means of securing the heel to the shoe.

It IS the primary object to provide an improved spikeheel for ladies shoes, including the use of a rigid unitary supporting body and shank together with a plastic molded cover therefor and incorporating means for efiectively securing the heel to the shoe.

It is a further object to provide a unitary spike-type heel in the form of a metallic base including a honey comb or apertured structure together with an integral depending heel shank and incorporating a plastic covering for the base of said heel which is permanently connected therewith and fixedly retains a wood securing plug within said base.

These and other objects will be seen from the following specification and claims in conjunction with the appended drawing in which:

Fig. 1 is a perspective view of the metallic base and shank for the present heel.

Fig. 2 is a perspective view of the completed heel with plastic covering.

Fig. 3 is a fragmentary perspective view illustrating the plastic covering by itself.

Fig, 4 is a perspective view of a slightly different form of heel lift.

It will be understood that the above drawing illustrates merely a preferred embodiment of the invention and that other embodiments are contemplated within the scope of the claims hereafter set forth.

Referring to the drawing, the present spike-type heel for ladies shoes includes a formed metallic base 11 of some light metal such as aluminum which has formed therethrough a honeycomb or porous structure as at 12 and 13 and has a conventional oval marginal shapeat its upper end as indicated at 14. Central aperture 16 extends down into base 11 for a portion of its depth as defined by wall elements 15. The honeycomb structure referred to is intended to mean a base having formed thereinto a series of apertures or openings adapted to interlockingly receive portions of a plastic covering molded thereover.

The upper forward portion of the metallic base has a slightly concave front edge 17. Lower portions of said base curve inwardly and downwardly in a substantially conventional manner and terminate in the integral elongated metallic supporting shank 20. Said shank at its upper end is peripherally enlarged with respect to adjacent portions of said base, defining ledge 19-21 which extends completely around the upper end of said shank.

The free end of shank 22 has an axial relatively short bore 23 projecting up thereinto adapted to receive a permeable plug 28, Fig. 2, as hereafter described. An enlarged permeable plug 24 is snugly nested down into aperture 16 in base 11 with its upper face substantially 2,925,671 r tre t d Feb. 23, 19st)- flash with the generally 'eofiea've upper petites orsaid base.

The assembly of Fig. 1, with the permeable'plug '24 therein, preferably constructed "of wood, then has a plastic covering 25 conforming to its general shape molded over the top of said base and around its slides, with the plastic cover extending down to and engaging ledge 19-21.

The thickness of plastic cover 25 is such that said plastic covering at its reduced lower end 26 smoothly merges on all sides with the corresponding contour of shank 20. The plastic cover is molded so as to interlockingly engage and project into the honeycomb or otherwise porous structure of the metallic base for the purpose of provid ing a secure interlock therewith to complete the heel assembly.

An additional important function is performed by the plastic cover upon the top of the base, namely the fixedly securing therein of the wood or otherwise permeable plug 24.

The plastic material in the finished article and upon the top of said base projects peripherally thereof on all sides and is longitudinally as well as transversely concave to conform with the heel portion on a ladys shoe to which it is secured.

The securing is in a substantially conventional manner, in that a series of nails are projected down through the heel portion of the shoe through the plastic cover and fixedly into the plug 24.

A top lift 27 of conventional construction, made of rubber, leather or composition substantially conforms to the shape of the shank 20 at its free end and is positioned thereover and secured to the lower end of the shank by a series of nails, which project through top lift and up into the permeable or wood core 28 secured within bore 23. This completes the heel structure.

A slight variation of top lift assembly is shown in Fig. 4 wherein the top lift 29 includes an integral upwardly extending formed shank 30, which is adapted for snug retaining projection up into bore 23 upon the lower end of shank 20. This construction eliminates the use of nails for securing the top lift 29 in position.

The base 11 and shank 20 of Fig. 1, and the completed heel of Fig. 2 are substantially to full scale, for illustration. It is contemplated, however, that there may be variations in the size and cross sectional shape of the various parts.

Having described our invention, reference should now be had to the following claims.

We claim:

1. In a spike-type heel for ladies shoes, a formed metallic base of a honeycomb structure having a central aperture extending down thereinto, and an elongated metallic supporting shank depending therefrom as an integral part thereof, said shank at its upper end being peripherally enlarged with respect to adjacent portions of said base defining a peripheral ledge, a permeable plug snugly projected into said aperture and having an end face flush with the top of said base, and a plastic covering molded over the top of and around the sides of said base extending down to and engaging said ledge, and smoothly merging with the contour of said shank, said covering entering the honeycomb apertures of said base interlocking therewith, enclosing said plug and fixedly retaining the same.

2. In the heel of claim 1, a central axial bore extending into the free end of said shank, a second permeable plug secured therein, a top lift upon the free end of said shank, and fasteners extending through said top lift up into said second plug. I
